Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration) but there may be multiple sores.
The consequences of untreated syphilis can be detrimental. If left untreated, syphilis can so severely damage the heart that one may enter heart failure. It can also cause neurological issues such as strokes and seizures and can eventually lead to blindness.
